SpongeBob SquarePants - Season 1 Episode 20

Hooky: When the mysterious "hooks" (fishing, that is) suddenly appear in Bikini Bottom, Mr. Krabs warns SpongeBob to stay away from them. Despite Mr. Krabs' scary tales of sea creatures winding up in gift shops or packed cans, Patrick convinces SpongeBob that there's no risk and the boys tempt fate by riding the hooks and jumping off for fun. Mermaidman and Barnacleboy II: SpongeBob wins the big prize from his favorite TV show, "The Adventures of Mermaidman and Barnacleboy" – The Conch Signal! Now he can summon the semi-retired super heroes whenever there's an emergency. Rather than keep getting signals for "emergencies" like opening jars, the duo take SpongeBob along for their patrol to see what real crime fighting is all about.
